C# running on a 168MHz Cortex-M4 with 1MB of flash and 192KB of RAM. This particular "module" replaces the older one that used a 72MHz ARM7 with 512KB of flash and 64KB of RAM.

Think smaller.

Might be worth looking into, bit pricey compared to Arduino though.

But the starter kit comes with a mainboard and a 4" LCD touchscreen which is pretty decent for small projects. The hardware is largely made by GHI Electronics...

Not sure if this would be suitable or not...

If you go to the company's website and actually look at the board and the better photos on the starter kit entry, you'll note that the cables are all standard 10-pin ribbons. In other words, the same kind of cables that are used for connecting serial ports to motherboards, but without removing one of the wires from the ribbon.

If something more Arduino-like is what you want, look at their Fez Panda-II. It's $39.95 and has Arduino-compatible headers.

Both boards are built around a 72 MHz ARM7 that just happens to have Microsoft's .Net runtime preinstalled. Don't want to use .Net? Rather develop for the bare metal? That's what the JTAG port is for.

Active power consumption 160 mA
Idle power consumption 120 mA
Hibernate power consumption 40 mA
Not bad but a bit high if you want it to be battery powered.

Yeh, it's an "arduino killer", why else would it have been made?

Stop playing fucking semantics to ignore the truth of the situation.

It's an overpriced "arduino killer" for people who've drunk the .net koolaid.

To compare with Netduino ($34.95)

Atmel 32-bit microcontroller
Speed: 48MHz, ARM7
Code Storage: 128 KB
RAM: 60 KB
2.1"x1.8"x0.5"

You get twice the speed for almost 4 times the cost.
The real win is memory. With 16MB RAM, you can actually get stuff done.

Why not go to the supplier and source exactly what you need?
